Merge tag 'pci-v6.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull PCI updates from Bjorn Helgaas: "Enumeration: - Rework portdrv shutdown so it disables interrupts but doesn't disable bus mastering, which leads to hangs on Loongson LS7A - Add mechanism to prevent Max_Read_Request_Size (MRRS) increases, again to avoid hardware issues on Loongson LS7A (and likely other devices based on DesignWare IP) - Ignore devices with a firmware (DT or ACPI) node that says the device is disabled Resource management: - Distribute spare resources to unconfigured hotplug bridges at boot-time (not just when hot-adding such a bridge), which makes hot-adding devices to docks work better. Tried this in v6.1 but had to revert for regressions, so try again - Fix root bus issue that dropped resources that happened to end at 0, e.g., [bus 00] PCI device hotplug: - Remove device locking when marking device as disconnected so this doesn't have to wait for concurrent driver bind/unbind to complete - Quirk more Qualcomm bridges that don't fully implement the PCIe Slot Status 'Command Completed' bit Power management: - Account for _S0W of the target bridge in acpi_pci_bridge_d3() so we don't miss hot-add notifications for USB4 docks, Thunderbolt, etc Reset: - Observe delay after reset, e.g., resuming from system sleep, regardless of whether a bridge can suspend to D3cold at runtime - Wait for secondary bus to become ready after a bridge reset Virtualization: - Avoid FLR on some AMD FCH AHCI adapters where it doesn't work - Allow independent IOMMU groups for some Wangxun NICs that prevent peer-to-peer transactions but don't advertise an ACS Capability Error handling: - Configure End-to-End-CRC (ECRC) only if Linux owns the AER Capability - Remove redundant Device Control Error Reporting Enable in the AER service driver since this is already done for all devices during enumeration ASPM: - Add pci_enable_link_state() interface to allow drivers to enable ASPM link state Endpoint framework: - Move dra7xx and tegra194 linkup processing from hard IRQ to threaded IRQ handler - Add a separate lock for endpoint controller list of endpoint function drivers to prevent deadlock in callbacks - Pass events from endpoint controller to endpoint function drivers via callbacks instead of notifiers Synopsys DesignWare eDMA controller driver (acked by Vinod): - Fix CPU vs PCI address issues - Fix source vs destination address issues - Fix issues with interleaved transfer semantics - Fix channel count initialization issue (issue still exists in several other drivers) - Clean up and improve debugfs usage so it will work on platforms with several eDMA devices Baikal T-1 PCIe controller driver: - Set a 64-bit DMA mask Freescale i.MX6 PCIe controller driver: - Add i.MX8MM, i.MX8MQ, i.MX8MP endpoint mode DT binding and driver support Intel VMD host bridge driver: - Add quirk to configure PCIe ASPM and LTR. This is normally done by BIOS, and will be for future products Marvell MVEBU PCIe controller driver: - Mark this driver as broken in Kconfig since bugs prevent its daily usage MediaTek MT7621 PCIe controller driver: - Delay PHY port initialization to improve boot reliability for ZBT WE1326, ZBT WF3526-P, and some Netgear models Qualcomm PCIe controller driver: - Add MSM8998 DT compatible string - Unify MSM8996 and MSM8998 clock orderings - Add SM8350 DT binding and driver support - Add IPQ8074 Gen3 DT binding and driver support - Correct qcom,perst-regs in DT binding - Add qcom_pcie_host_deinit() so the PHY is powered off and regulators and clocks are disabled on late host-init errors Socionext UniPhier Pro5 controller driver: - Clean up uniphier-ep reg, clocks, resets, and their names in DT binding Synopsys DesignWare PCIe controller driver: - Restrict coherent DMA mask to 32 bits for MSI, but allow controller drivers to set 64-bit streaming DMA mask - Add eDMA engine support in both Root Port and Endpoint controllers Miscellaneous: - Remove MODULE_LICENSE from boolean drivers so they don't look like modules so modprobe can complain about them" * tag 'pci-v6.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci: (86 commits) PCI: dwc: Add Root Port and Endpoint controller eDMA engine support PCI: bt1: Set 64-bit DMA mask PCI: dwc: Restrict only coherent DMA mask for MSI address allocation dmaengine: dw-edma: Prepare dw_edma_probe() for builtin callers dmaengine: dw-edma: Depend on DW_EDMA instead of selecting it dmaengine: dw-edma: Add mem-mapped LL-entries support PCI: Remove MODULE_LICENSE so boolean drivers don't look like modules PCI: hv: Drop duplicate PCI_MSI dependency PCI/P2PDMA: Annotate RCU dereference PCI/sysfs: Constify struct kobj_type pci_slot_ktype PCI: hotplug: Allow marking devices as disconnected during bind/unbind PCI: pciehp: Add Qualcomm quirk for Command Completed erratum PCI: qcom: Add IPQ8074 Gen3 port support dt-bindings: PCI: qcom: Add IPQ8074 Gen3 port dt-bindings: PCI: qcom: Sort compatibles alphabetically PCI: qcom: Fix host-init error handling PCI: qcom: Add SM8350 support dt-bindings: PCI: qcom: Add SM8350 dt-bindings: PCI: qcom-ep: Correct qcom,perst-regs dt-bindings: PCI: qcom: Unify MSM8996 and MSM8998 clock order ...
